102203-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102203-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,2,0 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 102203-20:
(8*1)+(7*0)+(6*2)+(5*2)+(4*0)+(3*3)+(2*2)+(1*0)=43
43 % 10 = 3
So 102203-20-3 is a valid CAS Registry Number.
